It is shown the advantages of the new flow chemical reactor with increased heat stress (CRIHS) with small-scale turbulence in the combustion zone of the superrich APG mixtures with oxygen, in which the kinetics of the process is near to the PFR model, compared to existing flow reactors. Using this model it is shown that the change in the seasonal composition of APG under equal initial conditions greatly affects the residence time, the volume of the combustion chamber, its heat stress, the temperature of combustion and the yield of acetylene. For the field of reactor construction for a given coefficient of excess oxygen it is proposed to compensate the seasonal changes in the composition of the APG by joint adjustable pre-heating of a reagent mixture and its total molar flow rate.KEYWORDS: associated petroleum gas, acetylene, synthesis gas, oxypyrolysis, heat stress, model of plug-flow reactor.

The acid and catalytic properties of the obtained systems were studied during the non-oxidative conversion of methane to aromatic hydrocarbons. It was shown that in the reaction of methane dehydroaromatization the activity of the Mo/ZSM-5 catalyst significantly depended on the value of the silicate module of the zeolite.KEYWORDS: non-oxidative methane conversion, Mo/ZSM-5, high-silica zeolite, nanopowder, acidity, silicate module.

In the proposed multi parametric method of determining influencing environmental factor its value is not variable, as it determines by external nature or external conditions that don’t depend on the researcher. The influencing environmental factor has many signs with different authenticities determining the value of this factor. It is required to determine such a set of weighting coefficients, in which the overall reliability of the assessment of this factor would reach a maximum value. Thus, the problem is reduced to analysis of linear scalar convolution optimized by selecting the weight coefficients. Multiplicative problem was formulated and solved to determine the extent of soil pollution by hydrocarbons by analyzing the reflectance spectrum of vegetation grown on this soil. Mathematically it is proved that the application of the method of multi criteria optimization in the system when carrying out a total diagnosis of many contaminated sites improves the accuracy of the result of 1.41 times.KEYWORDS: hydrocarbons, soils, pollution, optimization, functionality, reflective spectrum.
